Description
Technical Field
The present invention relates to a transverse looper for installation in a continuous line for the treatment of metal strip.
Background
In a continuous processing line including processing facilities for continuously performing processing such as annealing, plating, and coating while advancing a metal strip, even when the advancement of the metal strip is desired to be stopped on the loading side and the unloading side thereof in order to perform a coil replacement operation of a coil around which the metal strip is wound, the advancement of the metal strip in the processing facilities cannot be stopped. Therefore, a continuous processing line for a metal strip includes a mechanism called a looper that feeds a structure in which the metal strip is accumulated into a processing facility on a loading side and accumulates a structure in which the metal strip is fed out from the processing facility on a carrying-out side, so that the processing can be continued even when the running of the metal strip is stopped by a coil replacement operation.
As a transverse type looper for advancing a metal strip in a horizontal direction, for example, a transverse type looper having: a looping car at the front end, which has a driving force; and a plurality of support cars which support the metal strip between the processing facility and the looping car without any driving force, and the looping car and the support cars are connected by a chain, a wire, or the like (see, for example, patent documents 1 and 2).
Further, there are known a looper in which a support car is magnetically coupled (see, for example, patent document 3), and a looper control device (see, for example, patent document 4) in which a control device of a looper, which is a steel strip accumulation facility in a steel process line, is provided with two drive motors of the looper to form a large and small double looper, and is provided with a position detection device of each of the loopers, a tension setting device of the looper, and a tension gauge of the small looper, and a mechanism for changing a tension command of the small looper by a positional deviation between the large and small loopers to synchronously electrically control the large and small loopers, and for controlling the tension of the small looper by a feedback signal of the tension gauge.

Problems to be solved by the invention
In the case of the transverse looper connected to the aforementioned looper and support car having a leading end provided with a driving force by a chain or the like, the movement of the looper is started to feed the accumulated metal strip to the processing facility while stopping the rotation of the coil before the metal strip wound in the coil shape is completely unwound from the loading side. At this time, the looping car having the driving force advances while sequentially colliding with the plurality of support cars not having the driving force, and thus the tension acting on the metal strip fluctuates due to the continuous application of the impact and the mechanical loss of the support cars. In particular, in the case of a thin metal strip having a small allowable tension value, there is a possibility that the tension fluctuation due to the impact exceeds an allowable range, or the tension of the metal strip is relaxed, thereby causing a stop of the processing line and a defective product.
Further, in the case where the tension is required to be lower than the looper sections in the sections before and after the looper, the tension rolls provided between the sections may fluctuate in tension to cause slip between the metal strip and the rolls, thereby causing a slip mark to be applied to the metal strip, which may adversely affect the product. After the completion of the operations of cutting and welding the metal strip accompanying the replacement of the coil, the looping car is moved to the original position to accumulate the metal strip. At this time, since the looping car pulls out the plurality of support cars connected by the chain in sequence, the tension also fluctuates due to the impact thereof, and has the same adverse effect. The same occurs on the carry-out side.
In addition, even in a looper in which support vehicles are coupled by magnetic force, the impact generated when the support vehicles collide with each other or separate from each other is the same as in the case of using a chain.
The present invention has been made in view of the above conventional problems, and an object thereof is to provide a lateral looper in which fluctuation in tension of a metal strip is suppressed.
Means for solving the problems
The present invention provides a lateral looper for a metal strip in a continuous processing line, comprising: a fixed roller; a looper which has a winding roller that winds the metal strip together with the fixed roller, and which is movable to change a distance between the fixed roller and the winding roller in a direction in which the metal strip is conveyed, thereby being capable of changing an amount of accumulation of the metal strip in the lateral looper; and a main backup roller carriage including backup rollers for supporting the metal strip stretched between the fixed roller and the winding roller, and moving in the same direction as the loop carriage, wherein the loop carriage and the main backup roller carriage each include an independent drive device and are capable of moving independently, and the lateral loop tool includes one or more auxiliary backup roller carriages, one or more of the auxiliary backup roller carriages includes an auxiliary backup roller for supporting the metal strip stretched between the fixed roller and the backup roller, and one or more of the auxiliary backup roller carriages moves by being pulled or pushed by the main backup roller carriage.
The transverse type looper is characterized in that one of the one or more auxiliary support roller carriages adjacent to the main support roller carriage is linked to the main support roller carriage by a chain, the adjacent auxiliary support roller carriages are also linked to each other by a chain, and the one or more auxiliary support roller carriages are pulled by the chain or pushed by the main support roller carriage to travel.
The transverse loop machine is characterized in that the fixed roller is provided with a plurality of rollers in the up-down direction, the loop machine is provided with a plurality of winding roller units formed by arranging and configuring the winding rollers in the up-down direction, a plurality of winding roller pairs wind the metal strip of the fixed roller and sequentially send the metal strip to other fixed rollers, the main supporting roller machine is provided with a plurality of main supporting roller units formed by arranging and configuring the supporting rollers in the up-down direction, the auxiliary supporting roller machine is provided with a plurality of auxiliary supporting roller units formed by arranging and configuring the auxiliary supporting rollers in the up-down direction, and the loop machine, the main supporting roller machine and the auxiliary supporting roller machine move on the same track.
The transverse looper is characterized in that the looper is pulled by a winch via a wire rope in a direction away from the fixed roll to store the metal strip in the transverse looper, and the stored metal strip that has traveled in the direction of the fixed roll is discharged from the transverse looper by relaxing the pulling force of the winch and using the tension of the metal strip.
The transverse looper is characterized in that the main support roller carriage is connected to two winches disposed at opposite positions via a wire rope, and when the main support roller carriage is pulled by one of the winches and travels, the other winch feeds out the wire rope while keeping the tension of the wire rope constant.
The lateral looper is characterized by comprising a position detector for detecting a distance between the looper and the main support roller carriage, and the looper and the main support roller carriage travel while being held at a predetermined distance by the position detector.

In the present embodiment, for example, the transverse looper 6 used on the carry-out side of the continuous processing line 1 for the metal strip 2 will be described as an example. As shown schematically in fig. 1 of the continuous processing line 1, the horizontal looper 6 is provided on the loading side of the continuous processing line 1 in the same manner as the unloading side, and functions in the same manner.
The continuous processing line 1 of the present embodiment is configured to, for example, wind a metal strip 2 wound into a coil shape and feed the metal strip to a processing section 3 where a process such as an annealing process is performed. In order to continue the process without stopping the travel of the metal strip 2 in the process section 3 even when the amount of winding of the coil 2a around which the metal strip 2 is wound approaches the full value and the coil is replaced with a new coil core, a lateral looper 6 for accumulating the metal strip 2 between the cutter and welding device 5 and the process section 3 is provided on the carry-out side of the continuous process line 1, and the cutter and welding device 5 is used to cut the metal strip 2 processed so far, to remove the wound coil 2a, and to attach the metal strip 2 to a new coil core and weld the same.
In the following description, in the lateral looper 6, the process zone 3 side is referred to as an inlet side of the lateral looper 6, the cutter 5 side is referred to as an outlet side, and a direction from the inlet side to the outlet side is referred to as a conveying direction.
As shown in fig. 2 to 6, the lateral looper 6 of the present embodiment includes a fixed roll 7 which is fixed and is not driven, a winding roll 8 which is provided in a looper carriage 17 described later and winds the metal strip 2 together with the fixed roll 7, a backup roll 9 which is provided in a main backup roll carriage 26 described later, and a sub backup roll 10 which is provided in a sub backup roll carriage 29 described later. In the figure, the reference numeral 32 is a roll shaft of each roll 7-10.
The fixed roller 7 is rotatably provided between a pair of support columns 11 provided on the inlet side, and a plurality of rollers are provided at appropriate intervals in the vertical direction.
Fig. 4 is a front view of looping car 17. The winding roller 8 is rotatably provided between the long side portions of the vertically long rectangular frame 12, and a plurality of the winding rollers are provided at appropriate intervals in the vertical direction. A base 13 protruding outward of the frame 12 along the axial direction of the winding roller 8 is provided near the center of the frame 12 in the vertical direction.
In the looping car 17, the wheels 14 are mounted on running rails 18 provided along the conveying direction at intervals in a direction intersecting the conveying direction, and the frame 12 is supported at the center of gravity in a state of standing up via the diagonal stay 4 and is movable in the conveying direction. The wheels 14 are disposed in plural in the conveying direction so as not to fall down in the conveying direction. At this time, approximately half of the upper side of the winding roller unit 17a constituted by the frame 12 provided with the plurality of winding rollers 8 is positioned above the upper surface 18a of the travel rail 18, and approximately half of the lower side of the winding roller unit 17a is positioned below the upper surface 18a of the travel rail 18.
In a state where the loop carriage 17 is placed on the travel rail 18, the fixed rollers 7 and the winding rollers 8 are arranged at positions shifted from each other by a height corresponding to the diameter of the other rollers 7 and 8. The metal strip 2 supplied from the inlet side is wound around the uppermost winding roller 8, then wound around the uppermost fixed roller 7, and alternately wound around the fixed roller 7 and the winding roller 8 in this order from bottom to top, and then fed out from the outlet side. Between the coil 2a and the lowermost fixed roller 7, a plurality of guide rollers 35 fixed to the floor surface 19 are arranged to guide the metal strip 2 therebetween.
As shown in fig. 3, a looper wire 15a which can be paid out and wound by a looper winch 20 provided on the exit side of the lateral looper 6 is wound around each of the two left and right looper pulleys 16a on the base 13 at a winding angle of 90 °, and the end of the looper wire 15a is fixed to a fixing portion 36 on the exit side of the lateral looper 6.
The looping car 17 moves to the exit side by winding the looping car wire 15a by the winch 20 for looping car, and increases the amount of the metal strip 2 accumulated in the lateral loop machine 6 by enlarging the interval between the winding roller 8 and the fixing roller 7. Further, when the looper wire 15a is paid out by the winch 20 for a looper, the looper 17 is moved to the entrance side by the pulling force acting on the metal strip 2 by the winding drive of the coil 2a, and therefore, even if the pulling force is not applied, the interval between the take-up roller 8 and the fixed roller 7 becomes narrow, and the amount of the metal strip 2 accumulated in the horizontal looper 6 decreases.
Fig. 5 (a) is a front view of the main support roller cart 26, and fig. 5 (b) is a side view of the main support roller cart 26. The support rollers 9 are rotatably provided between the long side portions of the vertically long rectangular frame 21, and a plurality of them are provided at appropriate intervals in the vertical direction. The frame 21 has a base 22 protruding outward of the frame 21 in both sides along the axial direction of the support roller 9 near the center in the vertical direction. The support rollers 9 are rollers for supporting the metal strip 2 from below in order to prevent the metal strip 2 stretched between the fixed roller 7 and the winding roller 8 from slackening, and have a diameter smaller than the diameters of the fixed roller 7 and the winding roller 8, and 2 times the number of the fixed rollers 7 and the winding roller 8 are provided in order to support the metal strip 2 extending above and below the fixed roller 7 and the winding roller 8.
In the main support roller cart 26, the wheels 23 are placed on the travel rail 18, and the frame 21 is supported at the center of gravity in a state of standing up via the diagonal stay 37 and is movable in the conveying direction. The wheels 23 are disposed in plural in the conveying direction so as not to fall down in the conveying direction. In addition, the travel rails 18 may share the travel rails 18 of the looping car 17. Other tracks may be provided. Approximately half of the upper side of the main support roller unit 26a formed by the rollers 21 is located above the upper surface 18a of the travel rail 18, and approximately half of the lower side of the main support roller unit 26a is located below the upper surface 18a of the travel rail 18.
The first wire 24a that can be paid out and wound by the outlet-side capstan 27 provided on the outlet side of the transverse looper 6 is wound around the two left and right first pulleys 25a on the base 22 at winding angles of 90 ° on the outlet side of the frame 21, and the end of the first wire 24a is fixed to the fixing portion 36 on the outlet side of the transverse looper 6.
The second wire 24b that can be paid out and wound by the inlet-side winch 28 provided on the inlet side of the horizontal looper 6 is wound around the two right and left second pulleys 25b on the base 22 at a winding angle of 90 ° on the inlet side of the frame 21, and the end of the second wire 24b is fixed to the fixing portion 38 on the inlet side of the horizontal looper 6.
The main backup roller car 26 is moved to the exit side by winding the first wire 24a by the exit side capstan 27 and unwinding the second wire 24b by the entrance side capstan 28. The second wire 24b is wound by the inlet-side capstan 28, and the first wire 24a is unwound by the outlet-side capstan 27, whereby the main backup roller car 26 is moved to the inlet side.
The transverse looper 6 of the present embodiment is provided with four sub-support roller carriages 29, and the four sub-support roller carriages 29 passively move between the looper carriage 17 driven by the looper carriage winch 20, the main support roller carriage 26 driven by the exit-side winch 27 and the entrance-side winch 28, and the column 11 provided with the fixed roller 7. The sub backup roller carriage 29 is different from the main backup roller carriage 26 in that the first pulley 25a and the second pulley 25b are not provided, and has the same configuration as the main backup roller carriage 26. The backup roller 10 provided in the sub backup roller carriage 29 corresponds to the backup roller 9 of the main backup roller carriage 26. In the sub backup roller carriage 29, a sub backup roller unit 29a in which a plurality of backup rollers 10 are provided in a housing 33 corresponds to the main backup roller unit 26a of the main backup roller carriage 26. The four sub support roller carriages 29 are arranged between the support column 11 provided with the fixed rollers 7 and the main support roller carriage 26 in a state in which wheels 30 provided on the side surface of the base 34 are placed on the travel rail 18 and supported at the center of gravity.
In the main backup roller car 26 and the four sub backup roller cars 29, the adjacent backup roller cars 26 and 29 are coupled to each other by a coupling chain 31 (see fig. 2, 3, and 6), and when the main backup roller car 26 travels to the outlet side by the outlet-side winch 27 and the inlet-side winch 28, the adjacent sub backup roller cars 29 are sequentially pulled and moved to the outlet side while the coupling chain 31 is tensioned (see fig. 6 (b) → fig. 6 (a)), and when the main backup roller car 26 moves to the inlet side, the main backup roller car 26 moves to the inlet side while being in contact with the adjacent sub backup roller cars 29 and pushing the sub backup roller cars 29, and moves to the side of the column 11 provided to the inlet side while increasing the number of the accompanying sub backup roller cars 29 by the movement (see fig. 6 (a) → fig. 6 (b)).
At this time, the looper 17 and the main support roller 26 are driven by different looper winches 20, different exit winches 27, and different entry winches 28. The distance C between the loop carriage 17 and the main support roll carriage 26 is measured by a position detector 39 provided in these carriages.
In fig. 2, the position detector 39 (for example, a light-receiving and light-emitting beam sensor) is attached to both the looping car 17 and the main support roller car 26, but a sensor of a reflection type, an eddy current type, or the like may be attached to either the looping car 17 or the main support roller car 26.
As shown in fig. 6 (b), when the position detector 39 detects that the predetermined distance interval (for example, the length of the coupling chain 31) is reached after the looping car 17 starts moving to the exit side, the main supporting roller car 26 starts moving to the exit side at the same speed as the looping car 17 and travels while maintaining the predetermined distance interval, and when all the coupling chains 31 of the supporting roller cars 26, 29 are in the pulled state, the main supporting roller car 26 stops and the looping car 17 stops at a moment farther than the predetermined distance interval (position S in fig. 2). Such control is performed based on the distance (interval C) measured by the position detector 39. The replacement of the coil 2a is completed up to this point.
As shown in fig. 6 (a), when the position detector 39 detects that the distance interval is a predetermined distance (for example, immediately before the loop car 17 comes into contact with the main support roller car 26) after the loop car 17 starts moving from the stopped state on the exit side to the entrance side, the main support roller car 26 starts moving toward the entrance side at the same speed as the loop car 17, and thus the loop car 17 and the main support roller car 26 can be moved without contact.
As described above, according to the lateral looper 6 of the present embodiment, the looper 17 that moves to change the interval between the fixed roll 7 and the take-up roll 8 and the main support roll carriage 26 having the support roll 9 that supports the metal strip 2 stretched between the fixed roll 7 and the take-up roll 8 are independently driven and can move without contact with each other, and therefore the behavior of the looper 17 that applies tension to the metal strip 2 is not affected by the behavior of the main support roll carriage 26.
More specifically, the looping car 17 does not collide with the main supporting roller car 26 and receives an impact, and the looping car 17 does not pull the main supporting roller car 26, and therefore there is no impact at the start of pulling, and the tension of the metal strip 2 is not easily changed. Therefore, the lateral looper 6 can be provided which suppresses variation in the tension of the metal strip 2.
In addition, since the auxiliary backup roller carriage 29 is provided in addition to the main backup roller carriage 26, and the auxiliary backup roller carriage 29 includes the backup roller 10 that backs up the metal strip 2, the metal strip 2 can be more effectively suppressed from being deflected. Further, since the sub-backup roller carriage 29 is pulled by the main backup roller carriage 26 to move, the behavior of the sub-backup roller carriage 29 is not easily affected by the movement of the loop carriage 17. Therefore, the transverse looper 6 can be provided which suppresses the deflection of the metal strip 2 and suppresses the variation in the tension of the metal strip 2.
Further, since the take-up roll unit 17a included in the looper 17, the main support roll unit 26a included in the main support roll carriage 26, and the sub support roll unit 29a included in the sub support roll carriage 29 are supported and moved at the respective gravity center positions, the take-up roll unit 17a, the main support roll unit 26a, and the sub support roll unit 29a can be moved in a more stable state. For example, compared to the case where the winding roller unit 17a, the main support roller unit 26a, and the sub support roller unit 29a are moved by providing wheels at the upper end or the lower end thereof, the swing can be suppressed to be small. Therefore, the lateral looper 6 capable of further suppressing the variation in the tension of the metal strip 2 can be configured.
At this time, it has been confirmed that the driving of the main backup roller cars 26 causes the sub backup roller cars 29 to sequentially collide with each other or to move while receiving an impact by being pulled by the connecting chain 31, but the tension of the metal strip 2 between the fixed roller 7 and the winding roller 8 is not varied, and the product is not adversely affected.
Further, since the looping car 17 and the main support roller car 26 are moved by the looping car winch 20, the inlet-side winch 28, the outlet-side winch 27, the looping car wire 15a, the first wire 24a, and the second wire 24b arranged at predetermined positions, for example, like a self-propelled looping car and a main support roller car on which a motor is mounted, the motor, a driving part of the motor, and the like do not move, and the winches 20, 27, and 28 as driving sources are always at constant positions. Therefore, the transverse looper 6 can be easily inspected and maintained.
The above embodiments are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. The present invention may be modified and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
